To all whom it may concern:

Be it known that I, Mnoornno MAmNo, a subject of the Emperor of Japan, residing at the city and county oi. San Francisco and State of California, have invented neW and useful Improvement in Soy-Bean Food, of which the following is a specification.

My invention relates to the prcparution o'l" an edible food "from What is known as the soy bean (GZ z ce'w-c 3055a). This vegetable contains protein and rat in large quantities; end it is the object oi my invention to subject this material to a process which will rendcrit suitable for the preparation cl food.

1e soy bean contains u, large quantity oi "Water and oil, and in its normal condition cunnot be properly reduced and prepared tor food.

This invention consists in a process by which the substance is brought to such a condition that it may be prepared. into a atsblc food.

For this preparation the beans are lirst crushed by suitable machinery and ground into :ticur, after which the bran and refuse are separated from the llour in any suitable naunner. To manufacture the bean cheese the material is mined 'Witl'i sullicient cold "miter to form a paste. To this is added cold water in proportion suilicicnt to thin the mess, and the solution may then be leached. for an hour or two. it is then poured into boiling Water and thoroughly stirred. ll hen it hasboiled and is ready to run out of the pan, a small proportion of sweet or salad oil is added and the boiling continued until the foaming subsides. The edible oil has the effect oi the beans and gives the final product a very much better flavor; it also greatly increases the softness ol' the cheese and betters its condition for future use.

The mass is then laced in a deep vessel and a covering of thin sheet linen is placed over it. The boiling liquid is placed in a Specification of Letters Patent.

cloth bag and is squeezed until the thick liquid is forced through, care being taken not to drop any sediment into the strained material.

A solution of Epsom salts is then prepared, about one-eighth of a pound in a pint of Water, giving a bitter flavor. This solution is then gradually spread over the mass until a White deposit begins to show. After a short time this will separate entirely from the muss, leaving :1 light yellow liquid on the top. When the separation is entirely complete the water is poured oil? and the white solid material is placed. in a cloth and subjected to pressure until the Water has all run out. llhen the residue has become solid, it may be placed in cold Water and is their reudy for use. This residue which contains mainly protein, starch, and fat is then ready for cooking and other purposes.

Having thus described my lIlVQZllJlOll,Wl1fli3 I claim and desire to secure by Letters Pat ent isl. The process of preparing a food product, which comprises first crushing soy beans to a flour, mining the product With Water and heating it, adding a small proportion of edible oil, filtering the resulting mixture, prcciprtati the proteins in the filtrate, and separating them irons the bulk of the remaining liquid.

2. The process of preparing a food product, which comprises first crushing soy beans to a flour, mixing the product With water and boiling it, adding a small proportion of edible oil, filtering the resulting mixture, adding a proportion of Epsom salts to produce a precipitate, and separating the precipitate from the remaining liquid.

3. The process of preparing a food product from soy beans, which comprises first crushing the beans and then removing the flour from the crushed mass, leaching the flour, boiling the flour with Water and With a sweet or salad oil, filtering the solution, adding Epsom salts to cause a whitish de- Bill posit and finally compressing this dleposit to remove therefrom further quantities of liquid.

l. As an article of manufacture, a prooluct rich in proteins from soy beans and obtainable by pulverizing soy beans, leaching the pulverized product and then heating it with water and ultimately with an edible oil, filtering, causing the proteins in the filtrate 30 nlong with some fat and oil to separate from the bull: oi": the Water, and then compressing the separated rotein material to remove further quantities of liquid.
